Hello,
A few months ago i posted a question about connecting a bit of equipment to the mains power utility, and the practice of passing 20 Amperes down the power plant return (no neutral) in a 3-phase supply. I also dislike the practice of shorting the power plant return (PE) to the neutral (N) in the user equipment.
I have since been told to keep my mouth closed. This is the way we do it, although still I refuse to put what I call "dangerous information" into the BrE installation instruction card for installers in my workshop.
In this group i was asked repeatedly for the equipment and manufacturer, which i refused to deliver. Ok, well here it is. Scans from the manual and the source material. i put it all on an site:
Country = England (Bedford) where British and EU laws prevail.
